Hi All,
By using corosync-1.4.4 and openais-1.1.4. We encountered a
reproducable segmentfalt. By exams with gdb we found it failed
in log_printf_to_logs() at liblogsys.so.4.0.0 at the following
line:
while ((c = format_buffer[format_buffer_idx])) {
And the backtrace is:
log_printf_to_logs()
logsys_worker_thread()
start_thread()
clone()
Only release version have this issue. If I turn
--enable-debug when compiling, then it will not happen.
It can be reproduce by executing corosync-blackbox again and
again quickly and frequently while aisexec and its client
application is running (to let amf_dump_fn() really has
something to print).
Hi,
We had almost the same issue with libqb (withot corosync). When we
tried to make daemon from process we had to reinitialize logs.
Reinitializing didnt really worked (this option isnt supported) so
we changed code it a bit (just checking some variables etc), then we
got segfault on write (also only in release mode).
